SHIP STABILIZER.

Application filed May l1,

To all w71 om t may concer/n:

Be it known that I, STANLEY 'aiinoiisnn a citizen or' the United States of America, residing at Chicago, in the county oi Cool; and State of Illinois, have invented certain new and useful Im] irovements in Ship Stabilizers, ot which the following is a speciiication.

ThisI invention relates to certain new and useful improvements in ship stabilizers and has particular reference to that type of stabilizer employing water as a] ballast.

The primary object oi the invention resides in the provision of a stabilizer tor ships wherein a water passage or coinpartn ment is provided in the side walls ot the ship beneath the water line thereoit', the compartments being open at their forward ends adjacent the bow of the ship with sliding closure gates for the rear ends ci the compartments to con-trol the passage ot water therethrough.

The invention further embodies in a ship stabilizer oi the type above set i'ortli, the provision of gates for the front and rear ends of the stabilizing water compartments whereby either of the side comparti'nents may be iilled with water for stabilizing the ship and compensating tor laterally positioned freight carried thereby.

TWith these general objects in view and others that will appear as the nature ot the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully describe-d, illustrated in the accompanying drawings, and pointed out in the appended claims.

In the drawings forming a part ol? this application and in which like designating characters refer to corresponding parts throughout the several views:

Fig. l is a. side elevational view et a ship provided with a stabilizer constructed in accordance with the present invention,

Fig. 2 is a rear elevational view et the stern ot' the ship showing the outlet For the stabilizing water compartments,

Fiig. 3 is a cross sectional view taken on line III- III ot F l, showing the side stabilizing compartments,

view of modified torni of stabilizing water compartment and ship showing a closure for the entrance opening thereof, 1. Fig. 6 is a detail sectional view taken on lineAl-IMVI of Fig. 5, and

Fig is a horizontal tragiiientarv sectional view oi' the rear end ot the sliipshown ing one of the gates in its closed. position and the other gate shitted to an open posi'- tioh with thel stabilizing` compartment open. ite'nterriiig more in detail to the acconipanying drawings, and particular to F igures 'l toe, there is illustrated a ship enibodying side walls l. and decl( portions and o. The space within the body ot the ship beneath the lower decl: 2 carries longitudinally extending partition walls s@ joined together as shown in Fig. to torni a lreelson 5 secured to the keel ot the ship as illustrated, the partition walls d dividing' the space beneath the deck 2 into laterally positioned stabilizing water compartments G. Each side wall l of the ship atthe bow end thereof is cut away as at 7 to provide an entrance opening' for each compartment 6. the forward ends of the compartments be ing separated by the wall 8 as clearly shown in F ig. 4. The rear wall ot the ship is cut away as at 9 to provide separate outlets for the compartments 6 thereby permitting the tree passage of water through the side coinpartinents, adding to the weight of the ship beneath the water line thereof for purposes ot stabilizing the saine.

In the form of the invention shown in Figures 5 to 7, the bow end of the side wall a is cut away to provide an entrance opening 7a that is closed by a sliding gate l0 having a. rack bar l1 secured to the upper end thereoiI as shown in Fig. 5 and operable `by a pinion l2. rThe rear ends of the side compartments G are open as at 9d and are closed by sliding' gates 13 as shown in Fig. 7 that are operable in a manner similar to the gates l0.

roml the above detailed description oi' the invention, it is believed that the construction and operation tliereol will at once be apparent, it being noted that in the torin ot the invention shown in Figs. l to l the side ballast compartments 6 are open at both ends to allow a tree passage of water at a point below the water line of the ship tor the purpose of stabilizing the same.

In the form oll the invention shown iii Figures 5 to 7, either ot the compartments 6a may be filled with Water for ballast to stabilize the ship and compensate for the lateral positioning ot' 'freight within the ship.

fhile the torni ot the invention herein shown and described is what is believed to be the preferred embodiments thereof, it is nevertheless to be understood that various forms, modifications and arrangements of the partsniay Vbe rnade without departing,` 'from the spirit and scope ot the invention as claimed.

What I claim is l. 'In a ship having a keelson and a keel, partition 'Walls e\tendin, upwardly at an acute angle 'tromthc upper end oit said keelson, and side Walls extending,V upwardly at an acute angle 'l'roiu said keel, the upper ends o'l' said partition walls 'forming a juncture with said side -walls at thc central portions of the latter for devising' water coni- )artinents for stabilizino the shi i. F)

2. ln a ship, a keelson, a keel, partition Walls extending` upwardly at an acute angle from the upper end ot said keelson, side Walls extending upwardly at an acute angle from said keel, the upper ends of said partition walls Vr'orminscg a juncture With said side Walls at the central portions or' the latu ter for devising` `Water compartments t'or stabilizing the ship, and sliding gates cooperating with each end of said Water coinpartinents for controlling` the inlet and outlet of the 4AWater to and from the compartments.

3. In a ship, a keelson, a keel, partition Walls extending upwardly at an acute angle from the upper end of the keelson, side Walls. extending upwardly at an acute angle .troni said keel, the upper ends o" said partition walls forming a juncture with said side Walls at the central portions of the latter 'for devising water compartments for stabilizing the ship, gates associated 'with each end or' said water compartments `for controlling the inlet and outlet oit the water to and from the compartments, rack bars associated with the upper ends ot' said gates, and pinions cooperating With said rac-lr bars for sliding'the gates in vertical direction.

In testimony whereof l. aliix niy signature.
